CVE-2026-48772
Description
A flaw was found in ProxySQL, a proxy for MySQL and its forks, as well as PostgreSQL. A remote attacker can exploit this vulnerability by sending a specially crafted PROXY protocol version 1 (PP1) header with an 'UNKNOWN' protocol token. Despite the specification requiring these address fields to be ignored, ProxySQL incorrectly parses and uses the spoofed source address from this header. This allows an attacker to bypass routing and Access Control List (ACL) rules, potentially gaining unauthorized access to sensitive database operations or data intended for specific internal applications.
